When the study was conceived and when the study was funded, there was a genuine uncertainty regarding the appropriate treatment for patients with minimal to no arthritis and a degenerative meniscus tear. With this growing body of literature, however, there is more clarity on this question, and from an ethical standpoint, without genuine equipoise, discussing treatment options and recruiting patients into the study become problematic. The study design was then changed to a prospective observational study of patients with meniscus tears undergoing arthroscopic meniscectomy. The investigators will still be collecting the same data as in the prior randomized trial. The data are patient reported outcome questionnaires, MRI's, and gait analyses at time points from preoperative to two years postoperative. The investigators will also be collecting tissue samples at the time of surgery for the evaluation of inflammatory markers.
